' Application led November 24, 1890. Serial No. 372,516. (No model.)

To a/ZZ whom t nca/,y concern.-

Beit known that I, ASAHEL M. SHURTLEFF, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Atomizers, of which the following description, in connection with the accompanying drawin`gs, is a specification like letters and figures on the drawings representing like parts.

This invention has-for its obect to improve the construction of atomizers; and my invention consists in details of construction to be hereinafter described, and pointed out in the claims.

Figure 1 shows in side elevation an atomizer embodying this invention; Fig. 2,an enlarged vertical section of the cap or stopper and tubesupport thereon; Fig. 3, a sectional detail of the tube-support shown in Fig. 2; Fig. 4, an enlarged horizontal section of the liquid and air tubes and nozzle shown in Fig. 1, taken on the dotted line an; Fig. 5, an enlarged section of the atomizing-oriices and nozzle shown in Fig. l; Fig. 6, a side view of a modified form of atomizer to be referred to; Fig. 7, an enlarged sectional view of the cap or stopper and tube-support shown in Fig. 6; Fig. 8, a sectional detail of the coupling for the liquid and air tubes shown in Fig. 6; Fig. 9, an enlarged sectional detail of the liquid and air tubes, showing the atomizing-oriiices and nozzle containing them.

The vessel a has a Acap or stopper a', herein represented as metallic and screw-threaded to fit upon the screw-threaded neck of the vessel ct, a suitable washer being interposed to insure a tight connection. A tube-support a2 is erected on the cap or stopper d. The liquid-tube l) extends down into the vessel and up into the tube-support a2, as shown in Figs. 2 and 3. The rod b extends through the tube-support 0.2 at substantially right angles with relation to the liquid-tube b, said rod having two longitudinal passages through it, one, as 2, for liquid, and the other, as3, for air. The rod b is branched at its outer end into two flattened tubes b2 b3, which are separated a short distance, as shown in Fig. 4. The liquid-tube b, as represented in Fig. 3, communicates with the passage '2, and an air-forcing device, as the bulb c, is coupled to the rod b', which communicates with the air-passage 3.

A bearer for the atomizing-orifices is provided, it being represented as ablock d, having trunnions d d', one of which is made larger than the other, said trunnions fitting correspondingly-shaped holes in the flattened tubes b2 b3. Passages are formed through the trunnions and through the block, which terminate in the atomizing-oriiices. The trunnions d d are made diierent, one with Arelation vto the other, so that they may be noninterchangeable, in order that the trunnion with the air-passage will always be connected with the air-tube and the trunnion with. the liquid -passage with the liquid-tube. By means of the trunnions d d the bearer d may be rotated or moved independent of the liquid and air tubes. Y

A nozzle .n is detachably fitted on the bearer inclosing the atomizing-orices. This nozzle may be made of any suitable shape, and when in the full line position shown in Fig. 1 serves as a retaining-well for the condensed spray, and when reversed may be emptied without overturning the vessel. The nozzle n also serves as a shield for the atomizingorices,t`orming a chamber in which they can operate to produce the spray. The nozzle n is made detachable, so that another nozzle may be substituted, if desired, or that the device maybe used without a nozzle, and for the purpose of allowing the parts to be more easily cleansed. The bearer dis held in position between the two tubes b2 b3 by means of a retaining ring or device f, surrounding or inclosing the said tube and adapted to slide thereon, the said tubes being made to spread slightly out of parallelism, so that the nearer the ring is moved toward the bearer the tighter the said tubes will hold the bearer.

By making the bearer for the atomizingnozzles det-achable the parts may be readily cleansed.

Referring to Fig. 6, the liquid-tube m and a parallel air-tube fm are provided,'the'liq uid-tube fm having a screw-threaded end m2,

(see Fig. 8,) which receives a coupling m3, held on a stationary tube m4 by the annular Iiange m5. y The tubes m m have at their outer ends atomizing-oritices, (see Fig. 9,) and the nozzle is detachably fitted onto the tubes inclosing the atomizing-o'rices. By means of the joint connection shown in Fig. 8 the liquid-tube m may be rotated, and the air-tube IOC m Will be moved in a circle around the axis of the liquidtube as a center, and by means of such rotation the nozzle n may be overturned and emptied when desired without disturbing the other parts of the apparatus.

In Fig. 6 the tube-support d2 has a passage simply for theliquid and differsin this respect `.from the tube-support a2 shown inFigs. 2 and 3.

I do not desire to limit my invention to the employment of any specific form of atomizingorifices, and for some purposes the nozzle n may be fixed instead of detachable and yet subserve the purpose of a shield for the atomizing-orifioes, and I do not desire tolimit myself to the specific construction of bearer shown, as it may be varied and yet enable the spray to be directed in different Ways.

By flattening the tubes b2 b3, as shown, holes or sockets may be formed therein large enough in diameter to receive large-sized trunnions d CZ',- Whereas if said tubes Were made round such large-sized holes or sockets could not be made and still retain a small and light-Weight tube.

1. In an atomizer, a vessel and acap or stopper therefor, combined with liquid and air tubes, atomizing-orifices at the ends of said tubes, and a reversible condensed-spray-retaining nozzle containing said atomizing-oriiices,substantially as described.

2. In an atomizer,avessel and a cap or stopper therefor, combined With liquid and air tubes, atomizing-orifces at the ends of said tubes, and a detachable condensed -sprayretaining nozzle containing said atomizingorifices, substantially as described.

3. In an atomizer, avessel and a cap or stopper therefor, combined With atomizing-orifices and a detachable bearer therefor, having trunnions differing one from the other, substantially as and for the purposes set forth.

4. In an atomizer, a vessel anda cap or stopper therefor, combined with atomizin g-orices and a detachable bearer therefor, aliquid and an air tube between which said bearer is detachably held, and a movable retaining device, as f, substantially as described.

5. In an atomizer, a vessel and a cap or stopper therefor, combined With atomizing-oritices, areversible bearer therefor, and two flattened tubes, one for liquid and the other for air, between Which the said bearer is held, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
